I on microprobe U-Th-Pb analyses combined with cathodoluminescence imaging of zircons from a metaanorthosite from the Central Zone of the Limpopo Belt record five distinct events. The most concordant ages of cores of zircon yielded a weighted mean 207Pb/ 206Pb age of 334 ± 463.6 Ma, representing the protolith age. The unzoned overgrowths yielded four discrete groups with weighted mean 207Pb/ 206Pb ages of 3150 ± 15 Ma, 2614 ± 4 Ma, 2488 ± 22 Ma and 2009 ± 28 Ma, representing four possible metamorphic events in the Central Zone. This is the first time that a succession of several metamorphic events has been demonstrated in a single rock-type from the Limpopo Belt.
